Have you done comparisons with 4 bit and seen a noticeable difference for coding tasks?
No, I've just seen benchmarks showing most models start degrading around 4-5 bits. That's not to say they become useless, just that down to about 6-bits (with careful hybrid quantizations like unsloth where some of the layers aren't quantized or are quantized at higher bit depths) the quality isn't measurably degraded, but below that there are measurable differences in performance. People report good results from Dee…
